NUT-LOCKING DEVICE.

SPECIFICATION formingpart ofLetters Patent No. 661,059, dated November 6, 1900. Application filed January 29, 1900- Serial No. 3,109. (No model.)

To aZZ whom it may concernr with a recess 7, within which project the T Be itknown that I, JOHN E. LENHUL'I, a citiends of the lugs 2. The engagement of the zen of the United States, residing at Leetes lugs 2 with the recesses 7 prevent the with- Island, in the county of New Haven and State drawal f the rails endwise after the plates 55 of Connecticut, have invented certain new are placed inposition. Passing through the and useful Improvements in Nut-LockiugDesaid tie-plates and between the ends of the vices, of which the followingisaspecification, rails 1 l is the tie-bolt 8, and upon one end reference being had therein to the accompathereof is the hot 9, having a circular portion nying drawings. 10, around the periphery of which is cut a 6o My invention relates to improvements in plurality of gear-teeth. Integral with the nut-locking devices, and more especially to tie-plate 4 is the spring-cylinder 11, having a that class of nut-locking devices for preventcircular bore therein, and operative within a ing the unloosening of the tie-bolt nuts on a groove 12 in said plate is a locking-slide 13, rail-bond. which is provided with gear-teeth 14, which 5 (5 It is the object of my invention to construct are designed to engage with the teeth upon a device of this character of the fewest posthe nut 9. Projecting upwardly from one sible parts which can be economically conend of the said slide is an arm 15, carrying a structed and readily assembled. circular plate 16 of smaller diameter than the To these ends my invention consists in the bore of the spring-cylinder, within which it is i0 nut-locking device having certain details of movable lengthwise. Between said plate 16 construction andcombination of parts, as will and the inner end of the spring-cylinder 11 be hereinafter described, and more particuis the coil-spring 24. 1 larly pointed out in the claims. To secure the ends of two rails together by Referring to the drawings, in which like this device and lock the nut'against move- 75 numerals designate like parts in the several ment, the rails are placed end to end and the views, Figure l is a side elevation of my imtie-plates fixed in position with the lugs '2 enproved device, a portion of the spring-cylintering the recesses 7. The rails cannot now be der being broken away. Fig. 2 is a section moved endwise. The slide is then placed in thereof upon line A B of Fig. 1. Fig. 3 is a the groove 12 and the spring 24 is compressed 8o view of the device looking from underneath. by means of the clamp 17. The clamp-arm 18 Fig. 4 is a plan view. Fig. 5 is an end view is placed within the recess 19 and the screwof the spring-cylinder and slide. Fig. 6 is a point abuts against the rear end of the arm 15, side elevation of the slide. Fig. 7 is a view (see broken lines in Fig. 4,) and by rotating of the clamp for setting the slide. Fig. 8 is the screw 19 the slide is pushed inward and 85 a modified form of the device. Fig. 9 is a secthe spring 24 compressed. The bolt is then tiona'l view thereof upon line A B of Fig. 8. placed in position and the nut tightened there- Fig. 10 is a plan view of the abutting ends of on, after which the clamp 17 is removed and the rails used in the modified form, and Fig. the spring 24 immediately expands, exerting 11 is a view of the spring used therein. a pressure upon the plate 16 and moving the 0 4o .Inthe drawings the numerals 1 1 designate slide 13 so that the teeth 14 engage with the the rails, which are of the usual form and conteeth upon the nut 9. It is apparent that by struction, but provided upon the under side this construction there is always a constant with lugs 2 2, which are T-shaped, as illustightening pressure upon the nut 9,-which .trated in Fig. 3. Upon either side of the pressure is determined and only limited by 5 rails are tie-plates 3 and 4, having recesses the coil-spring 24.

5 in their inner faces, which only permit acon- I am aware that nut-locking devices have tact of the tieplates with the rails around the been previously made in which a slide has outer edges, thus overcoming any rocking been held in contact with a tie-bolt nut by a tendency that would ensue from a warped spring; but in these constructions there have too plate. The base portions 6 f said tie-plates always been two or more parts to the slide,

projectunderneath the rails and are provided an expensive device to make and easily disarranged. In my device it will be noted that there is but one piece to the slide. I have shown only one tie-bolt, which passes through between the ends of the rails; but two or more nuts can be used within my invention, if desired.

In Fig. 8 I have shown a modified form of the device. In this case the slide is of substantially the same construction as that shown in Fig. (5, with the exception that the arm has a hole 16 therethrough. A laterally-projecting head 20, having a hole 16 therethrough, is substituted for the spring-cylinder in the preferred form. The spring is made of circular 'wire in the form of a loop having outwardly-turned ends 21, which enter the holes 16 16. exactly the same manner as the slide above described.

In Fig. 10 I have shown a construction wherein the lugs upon the base of the rail, as illustrated in Fig. 3, are removed, and the meeting ends of the rails are at an angle to the sides thereof instead of being at right angles, as shown in Fig. 1. In this form the rails are provided with laterally-projecting lips 22 and the tie-plates with outwardly-projecting lugs 23 23, which abut against the end of the lips 22, as shown in Fig. 8.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character described the combination with a tie-plate having a base portion and a spring-cylinder integral therewith; of a tie-bolt; a nut provided with gearteeth threaded upon said tie bolt; and a spring-actuated slide within a groove in said tie-plate and movable in one direction by a spring within said cylinder, substantially as described.

The slide is actuated in- 2. In a device of the character described, in combination with car-rails; of a tie-plate upon either side thereof having engagement with said rails whereby endwise movement thereof is prevented; a tie bolt passing through said tie-plates; and between the ends of said rails; a nut threaded upon said tiebolt; a spring-actuated slide movable upon one of said tie-plates and having teeth thereon which engage with teeth upon said nut and movable in one direction by a spring, substantially as described.

In a device of the character described, in combination with a tie-plate having a base portion, upon which is a spring-cylinder; and

a groove extending through said cylinder and across said base portion; of a tie-bolt; a nut, provided with gear-teeth, threaded upon said tie-bolt; a slide movable in said groove, hav ing teeth which mesh in to the teeth upon said nut, and terminating at one end in a spring plate; and a spring'within said cylinder, having engagement with said plate whereby the said slide is moved in one direction, substantially as described.

4. In a device of the character described, the combination with the tie-plate t having the spring-cylinder ll thereon and the groove 12 therein; of a tie-bolt 8; a nut 9 provided with gear-teeth threaded upon said bolt; slide 13 within said groove, having teeth 14 thereon, and terminating at one end in the spring-plate 16; and a coil-spring 24 within said cylinder; all constructed and operating substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN E. LENHULT.
